has been compensated for b v means of a wedge and shoe cooperating with opposed edestal jaws, the shoe and wedge usually eing llanged, or in some instances .the wedge has been inserted. between 'the one jaw and a shoe in opposition to a. correspond,- ing shoe disposed on the remaining jaw, both shoes in the latter instance being flanged. Practice has demonstrated that the use of a flanged shoe and a flanged wedge, or of two flanged shoes with a wedge interposed between one of the shoes and one. jaw of the pedestal, is not a strolng' and durable organization in view of the fact that the flanges become broken and further interfere with and obstruct a ready adjust-ment to take up wear and also increase the cost of equi ment of the edestals b v reason of the mac ine work an expense incident to the formation of the flanges. Furthermore, the parts just referred to have not been easily replaceable, or in pursuing substitution it has been Vnecessary to introduce a wholly new shoe or wedge in place of a similar wom device or one that has become broken, in order to restore the pedestal in proper working condition. i

The object of the present invention is to dispense with the use of flanges on shoes and wedges for adjusting the driving boxes in locomotive pedestals, and substitute in lieu lolf' the flanges pieces of machine steel the thickness of the flanges ordinarily used on wedges and shoes and removably secure such pieces to the jaw frames so that when .they become worn bythe action of the driving boxes they can be renewed and thus materially reduce the expense in the con-2 struction and application of shoes and I' wedges to the jaw frames of pedestals and have a wedge that is free to adjust without the annoyance incident to ac-lose lit on the jaw frames as when flanged shoes and wedges are used. Furthermore, b y the Vuse Letters Patent. Patented Sept. 15, 19.08. j

to'v replace the flanges ordinarily embodied in the construct-ion of shoes and wedges, the said jaw frames adjacent the shoes and wedges are increased in strength and wear is prolongr the practical use of a pedestal.

The invention consists in the construction and Iarrangement of parts which will be more fully hereinafter specified in preferred form.

In the drawing; Figure 1 shows a side elevation of a pedestal with t-he invention applied thereto. Fig. 2 is a horizontal section on the line 2-2, Fig. 1. Fig. 3 is an elevation in detail of the wedge. Fig. 4 vis a Fig. 5 is a detail perspective View showing the improved form o f shoe. Fig. 6 is a del tail perspective view of the improved form of wedge- Fig. .7 is a detail elevation showing a slight modification of the wedge.

, Similar characters of' reference* are employed to indicate corresponding parts in the several views.

The pedestal shown comprises a top meniber 1 having two depending jaws 2 and 3. The inner wall of the jaw 2 is substantially vertical or at right angles to thelower wall of the top member l, as at 4, and the inner wall being the construction followed in oenerall Between these two jawsv2 and 3 thezbearing box is disposed and has a vertical movement in the usual manner.

The lower terminals of the jaws 2 and 3 are connected b v a suii able binder 6, and in some instances other analogous devices may be e111- ployed fer this purpose, the invention not being limited to the use of any precise binding means, and. as hereinafter explained, a part of the organization embodied in the features of the i vention will be modified to accommodate a variation in the kind of binding means thatvmay be used. At one side of the inclosed snace or pedestal containing the journal bearing or driving box, or againstthe wall which is usually the front, is arranged a stationary shoe 7 which is 'retained i in place by a bolt S, the shoe engaging at its i opposite extremities the top wl of the pedestal and a lower member 9 coperatlnv' with the lower extremity of 'the jaw' .Zjan Sthe binder means. the said shoe by such l motuiting being held against endwise movernent. `gainst the opposite wall 5 of the i pedestal is an adjusting member l() consistof the jaw 3 is slight-ly inclined as at 5, this y Par-ENT oruuon.,

1' of pieces of machinesteel on thejaw frames resisted to such an extent as to materially" transverse vertical section of the wedge.

ing of a wedge having an inner vertical wall 11 and an opposmgwall 12 which 1s inclined,

' the reduced extremity of the wedge being in engagement with the upper portion of the wall for obvious reasons. The length` of the wedge is less than the distance between the top wall of the pedestal space and a lower -member 13 coperating with the' binder'rand the lower extremity of the jaw 3 to permit of the necessary adjustment of the wedge.. The inner vertical face of wall 11 Aof the wedge directly contacts with the adjacent side or wall of the bearing box. The retention and adjust-ment of the wedge or adjusting member 1() is accomplished by a verv simple and effect-ive means. The lower enlarged extremity of the wedge has a longitudinal bore 14 formed therein and intersected byla counterbore 15 extending fully tln'ough from one face or wall to the other and of greater diameter than the bore 14;. Within the bore 15 a circular fulcrum or swivel nut 16 is disposed and has a screwthreaded opening 17 extending diametrically therethrough. adjusting-screw 18 is inserted upwardly through the member 13, the bore 14, and engages the screw-threaded opening 17, the diameter of the shank 'of the screw being materially less than the diameter of the bore 14 so that the wall of the latter bore is clear of the shank of the screw to permit the wedge to move in opposite lateral directions on the fulcrum or swivel nut 16 to compensate for irregularities in the pedestal as an entirety and which may ensue after prolonged use or to take up and provide for any irregular position of the journal-box that may exist.

It will be understood from the foregoing that the shank of the screw 18 always remains in vertical position and no injury will ensue to the threads of the shank by canting of the wedge or adjusting member as the latterwill move on the nut 16 which always remains in truc engagement with the threaded shank of the screw 18. The screw 18 is also engaged by a jam nut 19 which bears on the upper portion of the member 13 and revents the screw 1S from moving after adjustment. Instead of the single bore 14, counterbore 15, nut 16, and single screw 18 aduplicate construction may be used, as clearly shown by Fig. 7, to accommodate a differentiation in the characterof the binding means engaging the lower extremities of the jaws 2 and 3, and in this duplicate construction there are two bores 14 cach intersected bv a counterbore 15, two nuts 16, and a corresponding number of screws, lthe duplicate bores being arranged on opposite sides of the v vertical center of the wedge or` adjusting member 10. By turning the screw or screws ,-18 the adjusting member 1() may be moved sesgos l The essential feature of the invention, as herembefore noted, consists 1n the use of au flangeless wedge and a l'langelesr` shoe in op position to decrease the expense of manufac ture and avoid theannoyances and inconveniences attending similar devices having langes and as now commonly used. The

s roe and wedge oradjusting member is not particularly essential, but it has beenfound that a flat shoe made from machinesteel and a wedge or adjusting member formed from castiron givethe best results. In place of the lianges on the shoe and wedge, steel pieces 2() and 21 are applied to the opposite sides of the jaws 2 and 3 respectively adjacent to the shoe 7 and the wedge er adjusting member 10. The steel pieces 2O have their opposite side edges parallel andthe edges thereof adjacent the pedestal s ace are engaged by opposite portions of t e shoe 7, as clearly shown by Fig. 2. The pieces 21 have the `edges thereof engaged by the wedge 01 adjusting member 10 inclined correspondingly to the wall 5 and said inclined edges of the pieces 21 are dire .tly engaged by the opposite portions of th\wedfre. These pieces 2() and 21 are secured in p ace by rivets 22 and are removable, o when worn either one or both of the pairs \ofz"`pieces may, be replaced by similar pieces\fw thout requiring a. substitution of a new sho "or-a new wedge as is necessary in replacing shoes and wedges having integral flanges. T c pieces 20 and 21 also strengthen the portiohsonthe aws 2 and 3 which they enga-ge, and bein-g formed of machine steel they will be found tjuite durable and re )lacement thereof will-,only be necessary at long intervals. T he shoe Tand wedge 10 may also be replaced withoutlrenewing the pieces 20 and 21 or at a time whenzthe said pieces are in condition for further practical use and service. may be termed removable i anges coperating with but separate from the shoe 7 and wedge 10 and by the use of these pieces the cost of machine work and general construction of shoes and wedges for use with car pedestals is materially reduced.

It will be observed by reference to Fig. 2 that the wedge and shoe are slightly narrower than the outside faces 'of the jaws formed by the pieces or plates 21, the o bject of this diflerence in width of the parts just mentioned being to ermit the flanges o n the driving boxes to stri e the pieces or plates 21 without disturbing the shoe or wedge.

Having thus fully described thc invent-ion, what is claimed as new, is:

1. A car pedestal having a flangelcss shoe at one side and a ll.angelessg1einber or wedge specific kind of'metal used in forming the at an opposite side to engage a journal box,
